Afireworks rocket is fired vertically up. at its maximum height of 60.0m, it explodes and breaks into two
pieces, one with mass 1.20kg and the other with mass 0.30kg, both with horizontal initial velocities. in the
explosion, 0.960kj of chemical energy is converted to the kinetic energy of the two fragments.
what is the speed of each fragment just after the explosion? it is observed that the two fragments hit the
ground at the same time. what is the distance between the points on the ground where they land?

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
